' To all whom it may concern:

.Be it known that I, TOM .WnBB BEVAN,.

subject of the King of Great Britain,.residing at Nantyglo, Monmouthshire, Wales,-: have invented certain new and useful lmif provements in Surgical Bedsteads, of which connection passes placed in sz'tu. Fig. 2 is .an elevation of a portion of, the framework the following is a specification. v

This invention relates to improvements in the construction of surgical bedsteads, of that kind wherein the surface for the support of the patient can be placed at an inj;

clination to the horizontal plane, and which bedsteads are fitted with means for applying tension to the limbs of the patient.

= The object of the present invention is to provide a convenient and simple construction of such abjedstead which can beem- V ployed in the ordinary position of abedstead. and then present theusual appearance there.

of, while on the other hand by mechanical adjustment the bedstead can? be placed at 7 any desired inclination and can be, arranged to permit of extension devices being applied thereto.

According to thisinvention I make the bedstead to conform to the ordinaryorusual design, but with the legs at the foot thereof. extensible in length, so thatvwhen extended the ordinary supporting surface of the bedstead will incline downwardly from the foot toward the head, and when GhUS'lIlCllIlGd the bedstead can be readilymoved for cleaning purposes or the likewithont altering itsadjustment. Such a bedstead is provided with a detachable member over which the usual flexible weight-carrying connection passes which is employed in cases where extension is required, the said member be1ng ad usted insuch relation to the foot frame of the bedstead that the weight hangs clear of the framework when. the bedsteadiis'placed at an inclination to the horizontal, and the said,

. to any required position, ,but I; have found the roller shown to answer the purpose .wel1. .1211] will be readily understood by manumember is so constructed that sit-can be entirely removed when not requlred for use and leave thefoot frame of the bedstead un- Specification ofLetters Patent.

reference to, the gacco npanying ,drawi ngs, whereon- I Figure 1 shows a bedstead, according to this invention. with the bedstead adjusted to an inclined position, and, the member over which .the usual fiexible weight-carrying at the footend of the bedstead and If 3 is a transverse,- section of one of the side rails of the bedstead. j

:- Referring-to Fig. .1 ofthejgdrawings, the

detachable member jover which the flexible weight-carrying connection is to pass. consists of-two arms 1, 2, theends of which are ,connected together by arod, which rodcarries, in theinstance illustrated, a' revolublev tube ,or roller 3. The -arms 1,.2of thismem- ,ber por extension frame are adapted to be passed freely through -sockets or loops 4: (Figs. 1 and 2)., fixed on the vertical membets 5, 6 of the foot frame of the bedstead, the; said arms 1, Zextending when so placed upon each exteriorside of: the side frames --7, S; the arms, may be conveniently; formed .with holes as shown,;.while the sideframes 7, 8 are similarlyfiormed with a series of holes, and p ns, such as: 9, .1 n'ay be, passed through one. of. the holes in' each of the arms l, 2. an'd through correspondingholes1 Lin thesidev frames 7, 8, so that the roller 3 may be adjusted to anyrequiredposition exdingbeyond th fo ra-m f t ;stead,.and the flexible connections of the extension apparatus can then be, passed oyer {the roller 3landtheweight carried by such flexible. connections will hang v .clear of the beds v 1 7 ;,Obviously instead of; the roller g a ,loose ley can beadjusted lengthwise upon the rod facturers acquainted with the art, that numerous modifications of construction .may

be easily devised by whichthe roller 3 or I a rod or the like carrying a pulley can be detachably attached to the frame of the bedstead, whilevat the same time being ca-;

nature of my said invention and in what manner the same is to be performed. In the construction illustrated, by suit able adjustment of the arms 1, 2 the roller 3 can be adjusted so as to project more or or less beyond the foot frame of thevbedstead and can be varied to some extent in height, while at the same time when this extension frame is not required it can be entirely removed and leave the foot frame of the bedstead unencumbered.

I preferably construct the frame of the bed, such as the side frames 7, 8, either square in section or of channel section in which the flanges extend downwardly as for instance is illustrated at Fig. 3, so that clamps can be more easily fixed to such frames for enabling pulls in difierent directions'to be obtained in extension cases.

The legs of the head frame of the bedstead are of ordinary construction and are not extensible, while the legs of the foot frame of the bedstead are made extensible, and in the drawing at Fig. 1 the casters 1O carry stems 11 which are capable of sliding telescopically within the tubular legs 12 of the foot frame of the bedstead, and said telescopic legs are held at the required ex-- 'tension by any suitable means, but preferably'by a simple means such as shown in the drawings where a series of holes are formed through the stems 11, and holes through the tubular legs 12, so that the pins 13 can be passed through the said holes as indicated in the'drawing to retain the legs of the foot end of the bedstead at the length to which they have been adjusted.

Such a. bedstead it will now be understood can be used in the ordinary position of a bedstead and present the usual appearance thereof, by simply reducing the length of the legs 12 at the foot end to the same length as those at the head end and by rednoving the extension member comprising the arms 1., 2 with the rod 3; when such a bedstead is required to be employed in extension cases it will be obvious that it can be arranged at any desired inclination, and the detachable member over which the flexible weight-carrying connections are to pass can be easily placed in any required position. With the foot end thus raised to the proper extent the weight of the body of the r patient acts against the pull of the usual weight.

What I claim as my invention and desire to secure by Letters Patent is i 1. A surgical bedstead having in combination, means for elevating one end of said foot frame of the bedstead through which loops said arms are passed, said arms having a series of holes, and the longitudinal side frames of said bedstead also having a series of holes, pins to pass through the holes in said arms and through'the said holes in the said side frames of said bedstead to secure said arms in an angular position with said roller projecting beyond the foot end of said bedstead.

2. In surgical bedsteads; the combination of twonon-extensible legs at the head end of said bedstead, two extensible legs at the foot end of said bedstead, and a member comprising two parallel arms, one end of one arm and the corresponding end of the other arm being connected by a transversely extending bolt, a freely revoluble roller mounted on said bolt, a loop fixed externally on the outer side of each of the vertical members of the foot frame of the bed stead through which loops said arms are passed, longitudinal side frames of a section presenting'two'parallel vertical sides and a horizontal top portion, said arms having a series of holes, and the longitudinalside framcs of said bedstead also having Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
